An investigation on the effect of curing conditions on the mechanical and microstructural properties of the geopolymer concrete

Abstract Geopolymer concrete represents the future of green and sustainable concrete. It has a large impact on construction industry owing to its better performance than that conventional Portland cement This study aimed identify effect curing conditions physical, mechanical, microstructural properties specimens using ambient oven-curing. In experimental analysis, we tested slump setting time for physical properties, density drying shrinkage chemical compressive strength, indirect tensile modulus rupture, Poisson’s ratio, elastic mechanical rebound UPVT nondestructive x-ray diffraction, thermogravimetric analysis analysis. After it was concluded density, dry were higher ambient-cured oven-cured specimens, whereas those specimens. The tests, show are in quality strength cured diffraction showed had lower intensity mineral oxides matrix thermally stable up 800 °C retained 92% original mass, 94% mass
